Paper Abstract

The VISSR fiber optics assembly is a ring-shaped structure, attached to the radiometer aft optics support plate. Main components include a circular mounting ring, ten optical fibers, a right-angle prism, a flexible bellows, and eight filter blocks. In operation, light enters the prism and is bent to fall incident on the fiber ends. Fibers are routed from the common prism through the bellows into individual channels machined into the ring. Eight fibers serve as guides to carry light from the focal plane to detectors positioned symmetrically on the perimeter of the ring. At the prime focal plane they are bonded together in a linear array. The remaining two "end fibers" are used for alignment. Prism movement is used to compensate for thermally induced focus variations. The eight active fibers terminate into optical filter blocks which define the spectral cut-on wavelength.
